July 10, 1951 J. s; PHILLIPS AWNING Wm ADJUSTABLE LOUVERS' Filed me 29, 1949 attorney Patented July 10, 1951 UNITED STATES PATENT OFFICE Joseph S. Phillips, Fort Worth, Tex. Application June 29, 1949, Serial No. 101,995

1 Claim. 1

This invention relates to awnings for windows, doors, and the like, and has reference to improvements in ventilation awings.

An object of the invention is to provide an awning having easily adjusted movable louvers thereon and which louvers can be fixedly secured at various angles so as to admit desired amounts of sunlight.

Another object of the invention is to provide a sturdy construction in an awning having adjustable louvers forming a part thereof.

A further object of the invention is to provide an adjustable louver arrangement for awnings, and whereby said louvers may be easily and conveniently adjusted by crank means within the building where the awning is located.

These and other objects of the invention will become apparent from the following description and the accompanying drawings, wherein:

Figure l is a perspective view of the awning attached to the window frame of a'house, and showing the latter partly broken away so as to show the location of the operating crank.

Figure 2 is a vertical sectional view of the awning illustrated in Figure 1 and particularly showing the mechanism for operating or tilting the movable louvers, together with pawl means for securing said louvers in any desired position.

Figure 3 is an enlarged broken sectional view of the upper portion of Figure 2, and particularly showing the means employed for tilting louvers, and

Figure 4 is an enlarged broken sectional view illustrating the relative position of the actuating bar, one of the cranks operated thereby, and the location of the crank relative to one of the end plates of the awning.

The numeral l designates a pair of spaced vertical end plates substantially in the form of a quarter of a circle; however, it is to be understood that within the scope of the invention, these end plates may be in other forms, such as triangular, or shaped to accommodate casement windows. The end plates ID are joined at their upper and lower corners by horizontal frame members I l and I2 for supporting a structure on the outside of a building opening frame l3. The outer and upper edges of the end plates in are respectively inwardly flanged, as at l4, to support a former [5 of Z stock, as particularly shown in Figure 4. The depending webs or flanges of the formers l5 rotatably receive the ends of transverse parallel rods I'I, the latter having cranks l8 formed at corresponding ends thereof for pivform with the arcuate contour of the adjacent end plate 10.

Transverse louvers 20 are secured along corresponding longitudinal sides to the rods l1, said louvers being secured thereon by means of bending said corresponding edges around the lengths of said rods between the webs 16 of the formers 15. The entire construction, where possible, is preferably welded, although rivets, screws and the like may be used if desired.

A horizontal shaft 2| is supported parallel with the inner surface of the end plate In adjacent the actuating bar 19. The shaft 2| is supported at one end by means of a bracket 22 secured to the inner surface of the last referred to end plate In, whereas the other end of said shaft is supported in a bearing 23 mounted on and' near the inner edge of said end plate. The shaft 2| thence extends through a vertical frame member 24 and through an opening (not shown) in the frame 13 of the building. A crank 25 is secured to the last referred end of the shaft 2|.

A worm gear 26 is secured on the shaft 2| near the bracket 22 and is arranged for coaction with a segment gear 21 having an integral upwardly extending arm 28. The segment gear 21 is pivotally supported by the end plate l9 by means of a pin 21a. The upper end of the arm 2'8 is pivotally connected with one end of a link 29, and the other end of said link is pivotally connected with the actuating bar !9 near its upper end. A hood 3|] of sheet material is secured across the upper ends of the end plates l0 and extends outwardly so as to cover the upper inner edge of the uppermost louver 20. As particularly shown in Figures 2 and 3, the hood 3!] is upwardly flanged, as 3|, where it fits against the building frame l3, and is upwardly and outwardly flanged, as at 32, where it covers the inner edge of the uppermost louver 2D.

A vertically projecting plate 33 is secured to the vertical surface of the lower cross member l2 at the end thereof adjacent the end plate In carrying the segment gear 21, said plate being arranged for engaging notches 34 in the lower edge of a pawl 35. The end of the pawl 35 opposes the notches 34 and is pivotally secured to the lower end of the actuating bar 19.

In operation, the pawl 35 is raised from the holding plate 33, and by operating the crank 25, which thereby actuates the shaft 2|, worm gear 26, segment gear 21, and link 29, the actuating bar 19 is moved upwardly or downwardly. By reason of connection of the actuating bar l9 with the cranks I8, the louvers 20 may be raised or lowered simultaneously for admitting or excluding sunlight. By engaging the pawl 35 on the holding plate 33 and engaging one of the notches 34 on the latter, the louvers 24 may be secured and maintained in the angular position adjusted by the crank 25.

The described form of the invention may be made in many ways within the scope of the following claim:

What is claimed is:

An awning comprising a pair of spaced vertically disposed end plates each having downwardly and outwardly directed upper edges, a depending vertically disposed flange member supported by each of said end plates and inwardly positioned with respect to the latter, spaced parallel rods extending through and pivotally supported by said vertically disposed flanges, louvers secured to said rods between said flanges, cranks formed at corresponding ends of said rods, an actuating bar pivotally connected with said cranks, a segment gear linked with said actuating bar, and gear means supported and arranged for coaction with said segment gear.
